' Application filed Jul To: L I/ll whom it may concern:

Be it known that 1, WILLIAM: HENRY .,ADA1\/rs,'asubject of the King of Greet Britain, residing in the city and; district of Mon 5 tral, in the .l zrovince of Quebe filanr have invented eertaii'inew and useful 11nproyenicnts'in Methods of Making Rubber Hose; and 1 do hereby declare that the followingnis iuil, clear, and exact description is of the invention, such will enable others skilled in the art to which it eppertains to make and use the same. invention relates to a method of male rug rubber hose. 15 The object of inyi vention. is to provide a ine thod by wh ch st an dsrd-length hose may be Ins de coniprisi g an inner fabric and inner andouter coatin, of rubber.

A' further bject of my invention-is to pro- 2o vide ,a method by means of which the rubber will" not be overcured or burned and my invention consists of the steps herein described and claimed.

First. A tube of rubber is formed in any 2 5 suitable Way in the art\ of making rubber hose. x g

Second. The rubber tubes after being formed are placed in a vuleanir r in collapsedgco'ndition, preferably in bunches or bundles} ,Wlule in. the vulcenizerthey are partly cured, so that they may be handled. and 'so that they Will not stick or tear when inserted in a'woven tube or when a mandrel. is inserted into the artly-cured rubber tubes. 3 9 Third. The part y-cured rubber tubes" re then coated on their outside surface wf icementitious composition which will s i hinder heat.

i Fourth. The partly-cured and 40 coveredtubes are then drawn in de dition into a tubular Woven or knitted body. Being partly cured, the tubes of rubber do not stick or tear in this step, thereby making it possible to form standard-length hose-sec- 5 tions, it hitherto having been very difiicult to-draw a tube of uncured rubber into a section of Woven or kni tted tube. s

Fifth. By means of well-known apparatus applied to the ends of the tubes so inserted cementi into the tube of woven material the ends of the tubes are closed and live steam under pressure admitted thereto. The heat from the steam softens the cementitious material 0'11\ the outer surface of the rubber tube, and

the pressure of the steam distends the tube,

so that the coinentitious material enters into the interstices of the we 76D tube, and thereby bind" the tube of rubber to the we Fen e, to hat the inner tube is per-- iectly smooth... urtl ,r, the heat of the live stez-uu. turn-" cures is inner tube of rubber, which has been ps cured in the vulcanil ie any dang-er of overtube 's avoided, a a heated hollow as. woul e 1- case vii mandrel \Vitii used.

Sixth. As soon as the inn ube of rubber been suiiieiently 'exparufied and cured and the ceine'ntitious matter has joined the rubber tube to the Woven. tube the inner tube is cooled by the admission of water or otherwise, so that the curing oil? the inner tube is innnedietely stopped and the inner surface thereof. is sh htly hardened to permit the ready insertion. of a mandrel.

Seventh. A cold hollow mandrel is then inserted into the cooled tube, and bothof these being cold they readily slide upon each other. Asuitabie powdered lubricant, such as graphite or soapstone, may be applied, if necessary.

tlu L woven go of fabric is then wound about the out .1 s rface of the euro ube or" rubber, preferably two or three la v Tenth. The hose thus formed is placed in vuicanizer in bunches or bundles and u'zuolic ion oi. live steam. or the Wet ban-dag the ,r oi. the tube is prevent ed from application of wet ban ages, which also big-covering to the outer surface of serve to retain the hose in its proper shape,

being tightly wound thereon after the hol- It will be understood, of course, that the protecting-covering of wet bandages is removed as soon as the hose is fully vulcnnized or cured.

Heving thus fully described my invention, what I claim as new, end. desire to se cure by Letters Patent, is-- 1. The herein-described method of making fire-hose, which consists in partly curing a wholly--vulcunizable rubber tube, inserting the tube into u tube of fabric and causing it to adhere thereto, applying it coating of rubber tothe outer surface of the tube of fabric, l applying a rotecting covering to the outer surface of t e rubber to prevent o'v'ercuring, and fully curing the inner and outer rubber surfaces. 2. The herein-d escribed method of making fire-hose, which consists in partly curiur u l wholly-milcenizeble rubber tube, insertingthe tube into etube of fabric, further curing the rubber tube and causing it to adhere to the Woven tube, applying a coating of rubber to the outer surface of the tube of fabric, l applying n protectingczovering to the outer'l surface of th rubber to prevent overcuring, and fully curing the inner and outer rubber surfaces. 1 3. The herein-described method of making fire-hose, whch consists in pertiy curing o I whollyo ulcenizsble rubber tube, insertingthe-tube into a tube of fabric, closing the ends of the rubber tube and. admitting live steam to the interior of the rubber'tube, cooling the rubber tube, inserting a cold hollow mandrel into the rubber tube, applying coating of rubber to the outer surface of the tube of febri c, applfing a. removable protectthe ru bl to the tube of fabric, applying a outer surface of sensor her to prevent overcuring, and fully curing the inner and outer rubber surfaces.

t. The herein-described method of malu'n fire hose, which consists in partly curing a Wholly-vulcsnizeble rubber tube, inserting the tube into a tube of fabric, further curing a wholly-vulcanizable rubber tube, inserting the tube into the tube of fabric, nmintainin the tubes of rubber and fabric in a desire shape, spplyln an outer coating of rubber to the tube of fabric, applying at protectingcovering of fabric to the outer surface of the rubber to prevent overeuring, and fully curing the inner and outer rubber surfaces.

6. The herein-described method of making rubber hose, which consists in partly curing e wholly-vulcanizsble rubber tube, inserting the tube into the tube the tubes of rubber of fabric, maintaining shape, applying an and fabric in a desire outer coating of rubber protectingcontinuous wet fabric to the the rubber to prevent overcuring, and fully curing the inner and outer rubber surfaces.

In witness whereof I'have hereunto-set my hand in the presence of two witnesses.
